The Catalan journal Dau al Set (1948) and the artistic group of the same name are considered the most important manifestations of the post-war avant-garde.

The vast majority of its founding members (the poet and playwright Joan Brossa, the philosopher Arnau Puig and the painters Joan Ponç, Antoni Tàpies, Modest Cuixart and Joan-Josep Tharrats) lived in the same neighbourhood of Barcelona, and linked the disagreement with the repressive ideological situation and the limited creative possibilities of the period. They also shared a great creativity, sensitivity and sense of action.

The name of the magazine played with the idea of the impossible (Dau al Set meaning the seventh face of a dice that has only six), and expressed the intention of the group, located between the negation and confusion of Dadaism and the liberating creative expression of Surrealism.

The political circumstances hindered the desire of Dau al Set to influence the social environment, and the freedom of expression of its members was above all creative and artistic. As well, they fought to prevent the expressive forms established by the regime, they showed that repression can not stifle creativity and they were the triggers for new attitudes of free expression.
